Bargoon launched a potato straight up into the air with a speed of 16.67 m/s (up). What was the speed of the potato one second later??
Initial Velocity = 16.67 m/s
Accel of Gravity = -9.8 m/s^2
vf = vo + at Velocity final = velocity original + accel x time
vf = 16.67 + (-9.8)(1)
= 16.67 - 9.8 = 6.87 m/s
